Systematic measurement of pollutant levels in mesopelagic or midwater fishes could be a means for assessing the global status of ocean pollution in the future, as a companion to studies of large fish and marine mammals. For example, PCBs [ ] in the Southern California Bight [ ] have been mobilized by dredging of contaminated sediments from San Diego Bay.
Plastic microfibers are distributed globally in both water and air [,]. Algal species involved in HABs [ ] and ciliates implicated in coral diseases [ ] have also been found attached to marine microplastics. TEXT BOX 7: Climate-related collapse of a South African prawn fishery.
People have reported skin rashes, respiratory irritation such as sneezing, and a burning or itching in the nose or throat while swimming, visiting, or working at the beach during Karenia brevis red tide events . Organophosphate compounds, which are associated with reduced head circumference at birth a measure of delayed brain developmentdevelopmental delays, cognitive impairments, and autism spectrum disorder ASD [, ].
It is reflected in increased numbers of calls about ciguatera poisoning to poison control centers in the United States. The great importance of ocean monitoring in guiding the protection of human and ecosystem health was recognized in a seminal 2002 report that recommended establishing programs to monitor ocean pollution [ ].
Sea surface warming leads to range extensions of HAB species and to the appearance of algal toxins in previously unaffected areas [,]. Chemical pollutants are ubiquitous and contaminate seas and marine organisms from the high Arctic to the abyssal depths. Impacts of Ocean Pollution on Fish Stocks and Fisheries Increasing pollution of the oceans, climate change and ocean acidification can cause changes in the marine food web and these changes can influence the abundance and geographic distribution of commercially significant fish species that are important human food sources.
In concert with sea surface warming and ocean acidification, ocean pollution leads to increasing frequency and severity of HABs, destruction of coral reefs, and spread of life-threatening infections. Severe cases evolve to coma. In these circumstances, the food security of the juveniles becomes precarious, and stocks of key fish species can decline.
can leach into drinking water from household plumbing and service lines, mining operations, petroleum refineries, electronics manufacturers, municipal waste disposal, cement plants, and natural mineral deposits.
To continue the work, policymakers are now addressing current threats to the health of the harbor, including sea level rise, habitat destruction, and invasive species [ ]. Most of the mercury to which these populations are exposed originates from sources far away. In the oceans, pollutant concentrations are influenced by proximity to source, global transport patterns, and marine ecology.
Oil Spills Crude oil and petroleum products are complex mixtures of light and heavy hydrocarbons, toxic metals, and other chemicals. Need for monitoring will become increasingly great as the global climate continues to change, seas continue to warm, extreme weather events become more frequent, and human impacts on coastal, estuarine, and deep-ocean environments continue to grow. They are found in seafood . Microplastics have potential to harm living organisms through several mechanisms: Physical toxicity.
The first seven of these substances have been banned from use in Europe, and their discharges into the seas have declined, in some cases sharply.
