Re: Cleaning Hull in the water
Yes, and it didn't take long to find a source saying that chlorine beach is very bad when introduced into the environment:
"Unfortunately, chlorine also poses a significant risk to the environment, and was even used as a chemical weapon during World War I. Many countries have banned chlorine bleach or restricted its use in an effort to protect the environment and human health.
Manufacturers who use chlorine bleach often release it into local water bodies along with other liquid industrial waste. Once it reaches the water, chlorine reacts with other minerals and elements to form a host of dangerous toxins. These toxins, including dioxins, furams and PCDDs are often referred to as "persistent organic pollutants" because they linger in the water or soil and take many years to disappear. Greenpeace calls dioxin one of the most dangerous chemicals known to science, and warns that it can contribute to cancer, endocrine disorders and other serious health effects. The West Virginia University Extension also links chlorine-based compounds, like dioxins, with low sperm count, testicular cancer and breast cancer due to their ability to mimic human hormones."
