The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
The quality of diets in rodent feeding trials is crucial. We describe the contamination with environmental pollutants of 13 laboratory rodent diets from 5 continents. Measurements were performed using accredited methodologies. All diets were contaminated with pesticides (1-6 out of 262 measured), heavy metals (2-3 out of 4, mostly lead …
Trihalomethanes (THMs) and haloacetic acids (HAAs) are regulated disinfection by-products (DBPs); their joint reproductive toxicity in drinking water is unknown. The researchers aimed to evaluate a drinking water mixture of the four regulated THMs and five regulated HAAs in a multigenerational reproductive toxicity bioassay.

The transgenerational consequences of environmental contaminant exposures of aquatic vertebrates have the potential for broad ecological impacts, yet are largely uninvestigated. Bisphenol A (BPA) and 17α-ethinylestradiol (EE2) are two ubiquitous estrogenic chemicals present in aquatic environments throughout the United States and many other countries. Original Source
Pesticidal stress is very common factor today in human health and animal health. Most of the world s population depends upon fish food. Fishes can serve as bioindicators of environmental pollution since they are directly exposed to chemicals resulting from agricultural production via surface run off or in directly through …
Atmosphere, earth and water compose the environment. The presence of heavy metals in the environment has grown because of their large employment in some industrial and agricultural activities. Although these metals are terrestrial products, they flow into the sea through effluents and sewage or are directly discharged from industries placed …
Phthalates are used as plasticizers in soft polyvinyl chloride (PVC) and in a large number of consumer products. Due to reported health risks, di-isononyl phthalate (DiNP) has been introduced as a replacement for diethyl hexyl phthalate (DEHP) in soft PVC. This raises concerns since animal data suggest that DiNP may …
Mitochondrial dysfunction has been implicated in the pathogenesis of a variety of disorders including cancer, diabetes, and neurodegenerative and cardiovascular diseases. Understanding whether different environmental chemicals and drug-like molecules impact mitochondrial function represents an initial step in predicting exposure-related toxicity and defining a possible role for such compounds in the …
Mancozeb and its main metabolite ethylene thiourea (ETU) may alter thyroid function; thyroid hormones are essential for fetal brain development. In Costa Rica, mancozeb is aerially sprayed at large-scale banana plantations on a weekly basis. The objectives of the study was to (1) evaluate urinary ETU concentrations in pregnant women …
The groundwater in nearly 31 districts in Uttar Pradesh has been found to have a strong arsenic contamination which exposes the people to slow and consistent toxin. A technical report titled Arsenic toxicity in ground water of Uttar Pradesh shows that the concentration of arsenic in groundwater exceeds the Bureau …
In June, 2014, 20 experts from nine countries met at the International Agency for Research on Cancer (IARC; Lyon, France) to assess the carcinogenicity of perfluorooctanoic acid (PFOA), tetrafluoroethylene (TFE), dichloromethane (DCM), 1,2-dichloropropane (1,2-DCP), and 1,3-propane sultone (1,3-PS). These assessments will be published as volume 110 of the IARC Monographs.
This paper brings together over 250 published and unpublished studies on the environmental properties, fate, and toxicity of the four major, high-volume surfactant classes and relevant feedstocks. The surfactants and feedstocks covered include alcohol sulfate or alcohol sulfate (AS), alcohol ethoxysulfate (AES), linear alkylbenzene sulfonate (LAS), alcohol ethoxylate (AE), and …
Children today are sicker than they were a generation ago. The past few decades have seen a rapid rise in the consumption of synthetic pesticides. The world now uses about 2.3 million tonnes of pesticides every year, which is 50 times more than in 1950. The widespread use of pesticides …
A new investigation by Greenpeace International has found a broad range of hazardous chemicals in children's clothing and footwear produced by eight luxury fashion brands. Twenty-seven products were sent to independent accredited laboratories, and investigated for the presence of nonylphenol ethoxylates (NPEs), and certain products were also analysed for phthalates, …
Greenpeace has recently published a number of investigations showing that a wide range of textile products, manufactured and sold in many countries around the world, can contain residues of hazardous substances, including hormone-disrupting alkylphenols and their ethoxylates, reprotoxic phthalates, highly persistent per- and polyfluorinated chemicals, and – in some cases …
Cypermethrin is a synthetic pyrethoid mainly used against mango insect pests. Clams are good indicators of pesticide pollution and are known to be tolerant to pesticide accumulation. Acute toxicity experiment of Cypermethrin is carried out on estuarine clam, Marcia opima. The clam exhibited significant increase in protein content of gill …
Dietary exposure of children to Bisphenol A through feeding bottles under real use conditions was investigated. Polycarbonate is widely used in the manufacture of food containers and Bisphenol A can leach out into liquid food material. Three sets of six feeding bottles each from different brands were used in the …
Acute catastrophic events can cause significant damage to marine environments in a short time period and may have devastating long-term impacts. In April 2010 the BP-operated Deepwater Horizon (DWH) offshore oil rig exploded, releasing an estimated 760 million liters of crude oil into the Gulf of Mexico. This study examines …
Chronic exposure of bumblebees to two pesticides (a neonicotinoid and a pyrethroid) independently and in combination, at concentrations approximating field-level exposure, impairs natural foraging behaviour and increases worker mortality, with knock-on effects for brood development and colony success.
Mercury, a highly toxic heavy metal, has contaminated the environment of Sonbhadra in Uttar Pradesh. This new lab study by Centre for Science and Environment found the metal in not just soil and water samples, but also in people's blood. Singrauli, the powerhouse of India with massive coal reserves and …
