Acute ecotoxicity refers to harmful effects that occur from exposure to a hazardous substance for up to 15 days. These effects are caused by the interaction of the chemical with an organism's cell membranes, often leading to cell or tissue damage or death (Peake, 2016).
[4] [5] Biological hazards, also known as biohazards, are organic substances that pose a threat to the health of living organisms, primarily humans. This can include medical waste, samples of a microorganism, virus, or toxin (from a biological source) that can impact human health. Biological hazards can also include substances harmful to animals.
A biological hazard, or biohazard, is a biological substance that poses a threat (or is a hazard) to the health of living organisms, primarily humans. This could include a sample of a microorganism, virus or toxin that can adversely affect human health. A biohazard could also be a substance harmful to other living beings. [a]
[11] [12] Humans and other organisms, which consume shellfish and/or fish contaminated with persistent bioaccumulative pollutants, have the potential to bioaccumulate these chemicals. [2] This may put these organisms at risk of mutagenic, teratogenic, and/or carcinogenic effects. [2]
Bioaccumulation in turtles occurs when synthetic organic contaminants (i.e., PFAS), heavy metals, or high levels of trace elements enter a singular organism, potentially affecting their health. Although there are ongoing studies of bioaccumulation in turtles, factors like pollution , climate change , and shifting landscape can affect the ...

Things are not supposed to go there!” The research findings from Ross’ team, published in August 2023 , add to a slew of recent studies pointing to an alarming trend: microplastics are everywhere.
These harmful algal blooms are more likely to be produced at a dangerous amount when there is an excess of nutrients, the temperature is 20 °C, there is more light, and calmer waters. [17] Eutrophication and other contamination can lead to an environment that promotes cyanobacteria blooms . [ 17 ]
