A Need for Safe and Inclusive Green Space

The concept of space is diverse and is used across different disciplines. However, the article focuses on the everyday meaning of space i.e., physical landscape occupied by animate and inanimate objects alike. With the ever-increasing population and limited land resources ultimately gives way to struggle for space or to find solutions to increase the space. The pursuit to increase space has led to shrinking of green spaces, destruction of habitats among many others. A very unsustainable solution had been adopted by the governments and people to incorporate the beings on the stagnant resource.

The coming up of new cities – new households have also roped in new modern-day problems degrading the quality of living the cities – making the lower income families susceptible to harsh effects of diseases and disasters. Keeping this in mind, UNESCO has come up with 17 Sustainable Development Goals (SDGs). One of the SDGs is Sustainable Cities and Communities (SDGs 11) which is further broken in many different parts. Safe and Inclusive Green Spaces is one of them – the subject of the article.

Why do we need ‘Safe’ and ‘Inclusive’ ‘Green Spaces’?  Let’s start with the need for green spaces. It has been estimated that by 2050, 68% of the global population will come to reside in urban areas. Asia and Africa will see the influx of people to urban areas more than ever. However, the quality of living can never be assured. Study suggests that nine million people die every year due to the direct effects of air pollution.

One of the major problems that the urban areas face is the frequent appearances of ‘urban heat island’. Urban Heat Island refers to trapping of heat in between the built-up areas. The presence of built-up areas in close proximity and lack of green spaces disable the proper air circulation – trapping of heat – increasing the temperature by many folds – leading to the severe cases of heat stroke during the summer peak. Studies have confirmed that green spaces can easily mitigate the harsh effect of urban heat island. Other than this, green spaces will allow proper infiltration of rainwater – preventing water logging. It also filters the harmful particles – increasing the longevity of life. Green Spaces is a step towards the creation of harsh climate resilience cities.

The ‘Safe’ and ‘Inclusive’ component of the same is quite self-explanatory and can be interpreted in different ways as well. The article interprets these component as non-discriminatory measures. The cities are not only becoming the hub of crime rates but also of the subtle ways of exclusivity. The Spaces need to be constructed in such a way that it looks approachable for all the genders across all the sections. It should not scare one away and accepts the other. The need for safe and inclusive green spaces is because of the issues that surrounds us – crime rates; the harboring of hate for certain section sections and most important for the sustainable way of living – without fear, with quality.

If we focus on India, urbanization in India has followed quite the same path as other developing countries or some of the developed ones – concentration of population in certain cities of the country. Though the country does not have any primate states, it has primate cities at the regional level such as Ahmedabad, Patna, Mumbai, Delhi. The growing concentration in only certain parts of the country has also led to environmental degradation. Moreover, the paucity of space has led to evolution of cramped houses and walls on the fringes of the cities. The cities are also severely affected by various natural disasters – heatwaves, floods among many other extremes. The frequent changing course of the river in Bihar has been its major cause of worry. The drowning of Mumbai due to few hours of heavy rain yet again points to our lack of sustainable of planning. The death of over 1334 people in Ahmedabad in 2010 due to heat waves should drag our attention to the harsh effect of environmental degradation.

The governments across countries are formulating plans to survive the changing climate – the need of the hour also calls for individual and community level participation. Individually, people can partake in activities such as terrace gardening – contributing to the making of green spaces. Community can come together for the building of green parks, for taking up the work of cleaning alongside each other. An important role can be played by youth – to spread awareness and to bring in practice against littering, against wastage, towards sustainability.

Be Safe With Your Dinnerware

Are you staring at your plate right now with suspicious eyes? If so, then relax and take off that crease from your forehead. If you are worried about lead being present in your dishes, then we are here for you. Here all your doubts about how to test dinnerware for lead will be addressed and you don’t have to worry.

Safety is the first thing anyone wants while buying any product. You wouldn’t have thought about searching for lead in your dinnerware. Did you? Dinnerware is the most regularly used item in our homes, but to find that unsafe for us is disappointing. And also you shouldn’t be even asking this question. Think about it, you bought a nice dinner set from a respectable company, but here you are getting suspicious? Don’t worry any further. We will clear all your suspicions. Come on, let’s have a look at how to test your dinnerware for lead?

Why is Lead unsafe?

Lead is a harmful toxin that if ingested, may cause serious damage to the body systems. Children and pregnant women stay at a higher risk of health issues from the toxic effects of lead. You may have heard of lead poisoning too. It is very real and lethal.

Lead does not leave your body after entering. It accumulates there and due to this, even small amounts are harmful to health. You need to remove lead from your dinnerware so that you can eat your food safely.

Why is Lead Used in Dinnerware?

Lead is used in dinnerware for glazes and bright colors. It is basically used to beautify the dishes. The glazes that make the dishes shine like glass, the bright red color designs, these all are lead. It seems nice but it’s lethal. Lead also provides strength to the dishes and prevents them from moisture.

How Does Lead Enter Our Body?

There are many ways in which lead can enter our bodies. Let us point them out for you.

  1. If hot food is served on plates with glaze, the heat tends to extract the traces of chemicals from the surface and enter the food.
  • If you heat your food in the microwave, it can get lead into it. So don’t heat too many times.
  • Serving too much acidic food on a plate can also cause lead to enter the food. Acids tend to fast forward the process.

What Type of Dishes Contain Lead?

Dishes come in many varieties, so it can be hard to figure out the safest one. But we have something for you that can help. Now try to avoid the following things when looking for dishes:

  1. Antique dishes that may be passed down in your family from generations.
  • Heavily designed dishes, especially with bright colors like red, yellow, or orange.
  • Used dinnerware found in thrift stores or second-hand dishes you bought at a lower price.
  • Terra cotta dishes which are heavily glazed
  • Handmade dishes or pots.
  • Any dish with corroded glaze, or old dishes with worn-out designs.
  • Dishes with designs made above the glazed surface.

How to Test For Lead in Dishes?

You didn’t think you can check for the lead with plain sight, did you? No, you can’t. But there are some ways to test dishes for lead. One of them is to avoid the above mentioned types of dishes. Another useful way is by testing the dinnerware by home kit for testing lead in dinnerware.

Home Kit for testing lead in dinnerware is mainly useful for high content lead testing. It does not detect if there are only small amounts of lead in the dishes.

Another way is to send the dishes to a laboratory. But this may be a bit of absurd advice considering everyone doesn’t have access to labs and it is a bit expensive as well.

Method to Test For Lead With Home Kit

  1. Buy the chemically tested swabs, which are not very expensive.
  • Clean your dish with the swab.
  • If your dish contains lead, the lead detector on the swab with turn bright red indicating the presence of lead in your dish.
  • Or use a small chipped section of the glaze from the dish.
  • Peel a small part of the glaze and test it with the swab for more accuracy.

This method doesn’t tell you the exact amount of lead present in the dish. It is not much use but is fine for testing at home.

Method For Testing Lead in Laboratories

  1. Laboratories use X-ray systems to test for lead in dishes.
  • This method tells the accurate amount of lead present in the dish by using some electron reactions (which you don’t need to know about).

There are many ways to test for lead in laboratories. But some of them might damage the dish in the process. So this method is not feasible.

How to Reduce Exposure to Lead From Dishes?

The following points might be of some help:

  1. Stop using antique dishes
  • Don’t heat food in contaminated dishes
  • Don’t use highly glazed dishes for regular use
  • Stop storing food in contaminated dishes for a long time
  • Don’t wash the dishes containing lead in the dishwasher
  • Don’t serve acidic food on dishes containing lead. It speeds up the process.

Safest Lead Free Dinnerware

Choosing lead-free dinnerware for your safety is not that hard as it sounds. Just keep some points in mind next time while shopping for dishes.

  1. Choose the dishes with minimum designs
  2. Dishes with less glaze will be safe
  3. Plain white plates or dishes is definitely a winner
  4. Try to find less bright colored dishes
  5. We recommend more glass dishes. With them, you can be sure they are lead-free.
  6. If you are an appreciator for old, vintage dishes, you may want to restrict to the plain white ones.
  7. Melamine is considered to be the safest as it is more plastic than a glazed surface.

Now you are just a step away from buying lead-free dinnerware. Step out, go to that store, keep these few points in mind and find the perfect dinner set for you. And we hope now you know how to test for lead in dinnerware.

GOOD LABORATORY PRACTICES AND BIO-SAFETY METHODS

  1. When you arrive the laboratory, the first thing is that you must wash your hands with a disinfectant soap for your immediate sanitization.
  2. Eating anything in the laboratory area and smoking is strictly prohibited. Do not put anything in your mouth such as pencils, labels, or fingers. Do not store food in areas where microorganisms are stored.
  3. Purchase a lab coat and safety glasses and use them. Leave protective clothing in lab and do not wear it in non-lab areas.

  1. Avoid loose fitting items of clothing. Wear appropriate shoes (sandals not allowed) in the laboratory.
  2. Backpacks, purses and quotes should be placed in the cubbyhole by the front door of the lab. Place needed items on the floor near your feet, but not in the aisle.
  3. Disinfect work areas before and after use with 70% ethanol and fresh 10% bleach. The regular disinfection of the laboratory surfaces must be done using appropriate disinfectants like hypochlorite solution which kills almost pathogenic microorganisms.
  4. Label everything clearly.
  5. Caps and lids of reagents, solution bottles, and bacterial must be replaced properly in order to prevent contamination and petri dishes must not be opened directly in the lab unless absolutely necessary.
  6. Inoculating loops and needles should be flame sterilize in a bunsen burner before you lay them down.
  7. Turn of bunsen burner when not in use. Long hair must be restrained if bunsen burner are in use.
  8. Flame sterilization using alcohol must be done so carefully and it must be kept in mind that no papers or similar materials that can catch fire easily are nearby.
  9. Treat all microorganisms as potential pathogens and culturing of microorganisms must be done inside a special sterilized laminar flow hood and not outside it because many air-borne microorganisms can be spread.
  10. Wear disposable gloves when working with potentially infectious microbes and samples. If you are surely working with a pathogenic sample, you must handle it with extra care so that it doesn’t spill out on you or on any surface of the laboratory.
  11. Sterilize equipment and materials.
  12. Never pipette by mouth.
  13. Consider everything a bio hazard. Do not pour anything down the sink. Autoclave liquids and brought cultures to sterilize them before discarding.
  14. Dispose off all solid waste material in a biohazard bag and autoclave it before discarding in the regular trash.
  15. There are a special column of safety equipment in the laboratory which you must be aware of so that in case of any emergency you can make use of those safety equipments.
  16. Dispose of broken glass in the broken glass container.
  17. Dispose of razor blades, syringes, and sharp metal object in the “sharps” container.
  18. If by any chance, there is any type of spill of sample or culture or any media, you must immediately contact your instructor or mentor so that he/she can help you and find a solution to remove it from the surface. If you’re able to clean the spill by yourself do it immediately.
  19. In the same way, in case of any mishappening or sudden accident, you must immediately report to your instructor for the immediate help.
