Chlorine gas poisoning is an illness resulting from the effects of exposure to chlorine beyond the threshold limit value. Acute chlorine gas poisoning primarily affects the respiratory system , causing difficulty breathing, cough, irritation of the eyes, nose, and throat, and sometimes skin irritation .
Phytotoxicity describes any adverse effects on plant growth, physiology, or metabolism caused by a chemical substance, such as high levels of fertilizers, herbicides, heavy metals, or nanoparticles. [1] General phytotoxic effects include altered plant metabolism, growth inhibition, or plant death. [2]
However, the presence of chlorine in an organic compound does not ensure toxicity. Some organochlorides are considered safe enough for consumption in foods and medicines. For example, peas and broad beans contain the natural chlorinated plant hormone 4-chloroindole-3-acetic acid (4-Cl-IAA); [ 16 ] [ 17 ] and the sweetener sucralose (Splenda) is ...
Chlorine is detectable with measuring devices in concentrations as low as 0.2 parts per million (ppm), and by smell at 3 ppm. Coughing and vomiting may occur at 30 ppm and lung damage at 60 ppm. About 1000 ppm can be fatal after a few deep breaths of the gas. [18] The IDLH (immediately dangerous to life and health) concentration is 10 ppm. [129]
The World Health Organization has stated that "the risks to health from these by-products are extremely small in comparison with the risks associated with inadequate disinfection". [ 2 ] There are also other concerns regarding chlorine, including its volatile nature which causes it to disappear too quickly from the water system, and ...
Shelter-in-place recommendations and evacuation orders have been lifted Monday after a fire at a Georgia industrial plant caused a chemical reaction that prompted around 17,000 people to evacuate ...
The largest reservoir of chlorine resides in the lithosphere, where 2.2 × 10 22 kg of global chlorine is found in Earth's mantle. [2] Volcanic eruptions will sporadically release high levels of chlorine as HCl into the troposphere , but the majority of the terrestrial chlorine flux comes from seawater sources mixing with the mantle.
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
