Assessment of Chemical Contaminants in Sea Water: A Study of Heavy Metals and Organic Pollutants

Chemical contaminants in sea water, especially heavy metals and organic pollutants, pose significant threats to marine ecosystems and human health. This study investigates the concentrations of heavy metals (e.g., mercury, lead, cadmium) and organic pollutants (e.g., polycyclic aromatic hydrocarbons, pesticides) in sea water samples from coastal areas. The study analyzes the source, distribution, and environmental impact of these pollutants in three different regions: industrial, agricultural, and pristine coastal areas. Using advanced analytical techniques such as Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Gas Chromatography-Mass Spectrometry (GC-MS), the concentrations of heavy metals and organic pollutants were measured. Results indicate that anthropogenic activities, particularly industrial discharge and agricultural runoff, significantly elevate pollutant levels. These pollutants not only affect marine biodiversity but also pose risks to human health through the food chain. The paper concludes with recommendations for mitigation strategies to reduce pollution and preserve marine ecosystems
