Managing microplastic pollution is important for meeting sustainable development goals in India

As the most populous country in the world with a population of 1.42 billion, India is facing a mammoth challenge of achieving United Nations-mandated sustainable development goals (SDG) by 2030

In India, the demand for water is rising due to rapid population growth, urbanisation and increasing pressure from agriculture, industry and the energy sector.

Like the Anthropocene (human-dominated epoch), many scientists are using a new historical epoch, “The Plasticene”, due to the global distribution and abundance of microplastics. As the name suggests, microplastics are everywhere, from terrestrial ecosystems, to freshwater rivers, lakes, ponds, estuaries, seas and oceans, even in Antarctica.

Microplastic pollution especially harmful

  • The durability of plastic, which implies that plastic can take hundreds to thousands of years to decompose depending on the type of plastic and where it has been dumped.
  • In the oceans, plastic pollution impacts marine life, ocean health, coastal tourism and even human health.
  • Over the past few years, various news reports have shown that marine animals such as whales, seabirds and turtles unknowingly ingest plastic and often suffocate.
  • For humans, too, marine plastic pollution is harmful if it reaches the food chain. For instance, microplastics have been found in tap water, beer and even salt.
  • One of the first studies to estimate plastic pollution in human ingestion that was published in June 2019 said that an average person eats at least 50,000 particles of microplastic each year. Consumption of plastic by humans is harmful since several chemicals that are used to produce plastics can be

Measures taken by government:

  • India has pledged to ban all single-use plastics by 2022.
  • All offices of central and state governments and major PSUs have been told to prohibit single-use plastic products.
  • India has banned imports of solid plastic waste.
  • India has passed the Plastic Waste Management Rules, 2016 and introduced the Extended Producer Responsibility.

Plastic Waste Management Rules, 2016

  • It aims to increase minimum thickness of plastic carry bags from 40 to 50 microns.
  • Expand the jurisdiction of applicability from the municipal area to rural areas, because plastic has reached rural areas also.
  • Extended Producer Responsibility: To bring in the responsibilities of producers and generators, both in plastic waste management system and to introduce collect back system of plastic waste by the producers/brand owners, as per extended producers responsibility
  • Introduced collection of plastic waste management fee through pre-registration of the producers, importers of plastic carry bags/multilayered packaging and vendors selling the same for establishing the waste management system
  • Promote use of plastic waste for road construction as per Indian Road Congress guidelines or energy recovery, or waste to oil etc. for gainful utilization of waste and also address the waste disposal issue.

Way Forward:

3R’s +E Strategy

  • Reduce: To efficiently reduce plastic pollution, there is an evident need of reducing our usage of plastic.
  • Reuse: Many plastic items can be reused or used for different purposes. Before throwing plastic items, it is important to consider how they can be reused.
  • Recycle: Plastic recycling consists of collecting plastic waste and reprocessing it into new products, to reduce the amount of plastic in the waste stream.
  • Educate: Another crucial solution is education in order to increase awareness and behavioral change.

Legal wayout:

  • Law can be framed and used to tackle plastic pollution and support a circular plastics economy.
  • Policy shifts can reduce plastic pollution by incentivizing changes in both business and consumer behavior, as well as in plastic design, alternatives and recycling.
  • Governments can also impose taxes to deter the production or use of single-use plastics, or offer tax breaks, subsidies and other fiscal incentives to encourage alternatives to single-use plastic products.
  • Product standards, certifications and labeling requirements can be designed to educate the public on the environmental impacts of plastic, and on the health and safety hazards involved in their production and use.
  • Extended Producer Responsibility (EPR) programs can ensure that manufacturers maintain responsibility for single-use plastic products throughout the whole life cycles of those products.

World Fragile X Awareness Day 2023

Fragile X Syndrome

  • It is an inherited genetic disease passed down from parents to children that causes intellectual and developmental disabilities.
  • It is also known as Martin-Bell syndrome.
  • It is the most common hereditary cause of mental disability in boys. It affects 1 in 4,000 boys.
  • It’s less common in girls, affecting about 1 in every 8,000. Boys usually have more severe symptoms than girls.
  • People with FXS usually experience a range of developmental and learning problems.
  • The disease is a chronic or lifelong condition. Only some people with FXS are able to live independently.
  • The peculiar quality of this disease is that if it is inherited by the father, then it will only affect the daughter, but if it is inherited by the mother, then it can affect both genders.
  • Causes
    • It is caused by a defect in the FMR1 gene located on the X chromosome.
    • The defect, or mutation, on the FMR1 gene prevents the gene from properly making a protein called the fragile X mental retardation 1 protein.
    • This protein plays a role in the functioning of the nervous system.
    • The exact function of the protein is not fully understood. A lack or shortage of this protein causes the symptoms characteristic of FXS.
  • Treatment
    • It cannot be cured. Treatment is aimed at helping people with the condition learn key language and social skills.

Chemistry breakthrough makes fluorochemicals production safer

Fluorine

  • Fluorine comes from a calcium salt called calcium fluoride, or fluorspar.
  • Fluorspar is mined and then treated with sulphuric acid at a high temperature to release hydrogen fluoride (HF).
  • Hydrogen fluoride is then made to react with other compounds to create fluorochemicals.
  • Fluorine is a highly reactive element used to make fluorochemicals,
  • It is used to produce plastics, agrochemicals, lithium-ion batteries, and drugs.
  • Issues with hydrogen fluoride
    • A major downside of this process is that HF is an extremely poisonous and corrosive liquid that irritates the eyes and respiratory tract even at low concentrations.
    • It also requires special transportation and storage
    • Hydrogen fluoride spills have occurred numerous times in the last decades, sometimes with fatal accidents and detrimental environmental effects.
  • New procedure to obtain fluorine atoms
    • To avoid HF and to make the extraction process requires less energy, the researchers took inspiration from how the human body makes bones and teeth: through calcium phosphate biomineralization.
    • They ground fluorspar in a ball-mill with potassium phosphate.
    • While fluorine is very reactive, calcium atoms prefer phosphorus even more, so the milling created calcium phosphate and another compound with fluorine atoms. They called the latter Fluoromix.
    • When Fluoromix was reacted with organic compounds, it could create around 50 fluorochemicals with up to 98% yield.
