Abstract:
This study investigates the occurrence and distribution of chemical pollutants, including total petroleum hydrocarbons (TPHs), organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), anionic surfactants, and total organic carbon (TOC), in the Marine Protected Areas (MPAs) waters in the northern Persian Gulf. Water samples were collected from five MPAs during the winter and summer of 2022. The study identified significant seasonal variations, with higher pollutant levels recorded in winter compared to summer. Concentrations of ∑19PCBs (ng/L), anionic surfactants (µg/L), TPHs (mg/L), and TOC (mg/L) ranged from 0.72 to 4.66, 10 to 79, ND to 134.63, and 0.5 to 114.58 in winter, and from 2.49 to 5.05, 11 to 30, ND to 20.26, and 0.15 to 5.27 in summer, respectively. The pollution patterns revealed the Mond protected area as a major pollution hotspot, compromising its ecological health. The results highlight the critical need for targeted pollution control and enhanced conservation measures in the region's MPAs to protect biodiversity and marine ecosystems.

Types of Toxins
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
