Environmental toxicants comprise a number of man-made organic chemicals which may resist metabolism or their metabolites may persist in the environment and accumulate in the food chain. Some of these persistent chemicals are carried over long distances via the atmospheric transport and can have biological effects in fish, wildlife and humans. In this review the relationship between structure of these chemicals, their mode of action and their possible roles in adverse developmental and reproductive processes in humans will be discussed. The focus will be on model polychlorinated biphenyls and dioxins, organochlorines, phthalates, a constituent of cigarette smoke (benzo-a-pyrene), synthetic polymers (polybrominated diphenyl ethers and polyfluorinated compounds), and a fungicide (vinclozolin).

Melatonin (Mel) is a tryptophan-derived (N-acetyl-5-methoxytryptamine) molecule. In the present study, role of Mel in the regulation of various anaplerotic enzymes is discussed in relation to N metabolism and H-ATPase activity in mung bean under Cd stress. The application of Mel to the Cd-stressed mung bean seedlings was remarkable in improving the activity of hexokinase (35.

Aquatic toxicology, as a result of industrial and agrieqcultural effluences, has become a global concern impacting not only the well-being of aquatic organisms but human health as well. The current study evaluated the impact of four toxic trace elements (TTEs) Cadmium (Cd), copper (Cu), lead (Pb), and nickel (Ni) in three organs (liver, gills, and muscles) of five fish species viz, Rita rita, Sperata sarwari, Wallago attu, Mastacembelus armatus, and Cirrhinus mrigala collected from right and left banks of Punjnad headworks during winter, spring, and summer. We investigated the accumulation (mg/kg) of these TTEs in fish in addition to the human health risk assessment.

Background: The skin, with its robust structural integrity and advanced immune defense system, serves as a critical protective barrier against environmental toxins and carcinogenic compounds. Despite this, it remains vulnerable to the harmful effects of certain hazardous agents.
Objectives: This study aimed to investigate the chemopreventive potential of β-caryophyllene (BCP) in mitigating 7,12-dimethylbenz[a]anthracene (DMBA)-induced skin carcinogenesis, focusing on the modulation of apoptosis and PI3K/AKT signaling pathways.

The human body gets exposed to a variety of toxins intentionally or unintentionally on a regular basis from sources such as air, water, food, and soil. Certain toxins can be synthetic, while some are biological. The toxins affect the various parts of the body by activating numerous pro-inflammatory markers, like oxidative stresses, that tend to disturb the normal function of the organs ultimately.
