Hilsa, Bangladesh’s national fish, has been found contaminated with microplastics and cadmium, raising serious concerns for human health, Fisheries and Livestock Adviser Farida Akhter said on Saturday. "Industrial effluents from Narayanganj and other districts are flowing into the Shitalakshya and eventually the Meghna River, posing a severe threat to hilsa and other aquatic life," Farida Akhter said at the third convocation of ASA University Bangladesh (ASAUB) held at the Bangladesh-China Friendship Conference Centre in Agargaon. The adviser warned that hilsa contains harmful substances such as microplastics, lead, and cadmium, which is extremely alarming.  "Industrial waste threatens the very existence of hilsa and other aquatic creatures. Keeping our rivers pollution-free is a vital national duty—not just the government’s responsibility, but one that requires active public participation and awareness," she said.  Farida added that the Ministry of Fisheries and Livestock is responsible not only for cattle, goats and poultry but also for the protection of all animals, including dogs and cats. Without proper vaccination, dogs are at higher risk of rabies and other diseases, the adviser urged people to fulfill their responsibilities towards animals. Addressing students, she encouraged youth to take an active stance against corruption, environmental pollution, and unhealthy practices, emphasizing that protecting the nation for future generations is everyone’s duty. Highlighting the importance of natural resources, the adviser said, "Bangladesh is not a poor country. Our people’s skills, natural resources, potable water, crop seeds, and genetic resources are our greatest strength. Future global conflicts may revolve around water, seeds, or natural resources. Protecting these resources and ensuring the nation’s security is a critical responsibility for the younger generation." She also urged students to remain health-conscious, warning that smoking and tobacco use cause severe health problems. "Boys and girls often believe smoking or using drugs makes them ‘smart’ or fashionable, but in reality, it leads to heart disease, cancer, and other illnesses. A new law to control tobacco use has recently been enacted and is mandatory for everyone." Farida advised students to maintain the dignity of their degrees through good conduct, professionalism and character. Hilsa prices soar further putting this beloved fish beyond reach Around 4,000 students received degrees at the convocation, including 2,096 undergraduates and 1,900 postgraduates. The adviser also presented six students with the Chancellor’s Award and nine students with the Vice-Chancellor’s Award for outstanding performance.  

A study by the Autonomous University of Barcelona reveals that commercial tea bags made from polymer-based materials release harmful microplastics. Tea bags are popular for offering a convenient and comfortable tea-drinking experience, allowing users to easily dip and enjoy their brew. However, the material used for the outer layer of tea bags can actually have a negative impact on health. Commercial tea bags, which are made of polymer-based material, release millions of nanoplastics and microplastics when infused and release millions of microplastics when in use. According to a study by the Autonomous University of Barcelona, food packaging is a major source of micro- and nanoplastic (MNPL) contamination and inhalation and ingestion are the main routes of human exposure. The capacity of these nanoplastic and microplastic particles to be absorbed by human intestinal cells, and are thus able to reach the bloodstream and spread throughout the body. A twice-yearly shot could help end AIDS Researcher have successfully obtained and characterised micro and nanoplastics derived from several types of commercially available tea bags. The UAB researchers observed that when these tea bags are used to prepare an infusion, huge amounts of nano-sized particles and nanofilamentous structures are released, which is an important source of exposure to MNPLs. The tea bags used for the research were made from the polymers nylon-6, polypropylene and cellulose. The study shows that, when brewing tea, polypropylene releases approximately 1.2 billion particles per milliliter, with an average size of 136.7 nanometres; cellulose releases about 135 million particles per milliliter, with an average size of 244 nanometres; while nylon-6 releases 8.18 million particles per milliliter, with an average size of 138.4 nanometres. "We have managed to innovatively characterize these pollutants with a set of cutting-edge techniques, which is a very important tool to advance research on their possible impacts on human health," says microbiologist Alba Garcia-Rodriguez, from UAB.

Plastic is choking Bangladesh's drains, canals, and rivers. Around 1,700 tonnes of plastic waste is produced in the country every day and only half of it is recycled, according to the Department of Environment. In Dhaka city alone, plastic waste has gone up more than 3.5 times from 178 tonnes per day in 2005 to 646 tonnes per day in 2020. Of that 646 tonnes, only 37 per cent is recycled, and mostly by the informal sector, according to the World Bank.  It is almost impossible to imagine a day without any use of plastic. Clogged drains, bags fluttering in the wind, masses of plastic piled in dumps, and road corners have become an everyday reality in Bangladesh.

 Microplastics have been found to be omnipresent in rivers across Europe. 

Geneva, Aug 22 (AP/UNB) — The World Health Organization says the levels of microplastics in drinking water don't appear to be risky, but that research has been spotty and more is needed into their effects on the environment and health.
