Louisiana DEQ online map: don't eat fish here, do not bathe there Environment



The recently created interactive map allows people to know whether contamination caused Louisiana waterway insecurity to swim, and tells fishermen whether it's safe to eat their catch.

There are 58 lakes, ponds and other waterways on the map where the fish are caught, the bottom is too polluted for safe swimming, or both. Most limit fish or shellfish eating; two also warn of swimming. Two others warn only about swimming

The biggest advice covers all the waters of the Gulf of Mexico – almost 1200 square miles (3108 sq. Km).

Clicking on the fish and fish hook gives you an advisory. Increased and larger water bodies in the affected areas appear dark blue. These areas are also clickable, but are approximate ̵

1; there are no boundaries between the dark and light blue areas adjacent to the environment, scientist Al Hindrichs said by e-mail on Friday

"Be sure to read the details", he said in an interview with Baton Rouge on Wednesday. This is because the recommendations depend on what was found in the fish in the area and how much they were, so they are very different.

For example, state says nobody should eat fish from Capitol Lake in Baton Rouge. The list of Supreme Calcasieu Estates contains only crab fat. For 83 miles along the Tens River, advisory states only "Long-term fish consumption can pose a health risk".

Gulf tips are complicated. Most people are advised not to eat more than four 8 ounces per month of fish caught in public waters except mackerel. People should eat no more than two meals a month when mackerel – and only if the fish is less than 39 inches long. Women of childbearing age and children under 7 years of age should not eat king mackerel and no more than one meal per month from cobia, bluefin tuna and larger amber.

In the advisory language, "one food" means 8 ounces. [19659002] The tips also describe which substance, heavy metal or other substance is causing the problem

In Lake Capitol, these are chemicals called PCBs. In the parish of the Calcasieu and Cameron parishes, crab fat found PCBs, dioxins and furans. Dangerous DDTs and toxaphenes currently banned by Madison, Tens and Catahoulos along the River Tens

These are the exceptions: nine tips for one or another type of organic compound, and the other 49, including the Gulf waters for mercury, said Hindrichs

. fish are "very widespread", not because there is more mercury in the water, Hindrichs said. in a letter.

He said that although some mercury could have entered other waterways, including parts of the Ouachita Basin, from old oil and gas meters, it left the atmosphere in most areas. If it is a prerequisite for it to move from elemental mercury to a highly toxic organic compound called methyl mercury, it can easily work up the food chain, he said.

Every tip is a result of state environmental quality departments,

Hindrichs said the map grew in December, while Lake Sibley, the Natchitoches reservoir, was removed in early January after there were enough fish samples that appeared to be clean PCBs.

Most tips offer limits anywhere from 8 ounces per week to six 8 ounces per year. Recommendations may depend on where the fish species are in the food chain, because the fish that eat other fish live in the mercury they ate.
