Differential Impact of Organic Vanadium Compounds on Human Health
Published in Debasis Bagchi, Manashi Bagchi, Metal Toxicology Handbook, 2020
Satinath Mukhopadhayay, Bidisha Mukherjee
The common symptoms of vanadium poisoning are cough with expectoration, ear/nose/throat irritation, headache, palpitation, etc. Greenish discoloration of the tongue is a reliable sign of vanadium toxicity in humans. Organic vanadium compounds are much less toxic than the inorganic compounds. Diabetic rats receiving organic compounds did not show any gastrointestinal side-effects and did not develop diarrhea (32). In addition to gastrointestinal discomfort, other toxic effects of vanadium salts include hepatotoxicity, nephrotoxicity, teratogenicity, and reproductive dysfunction (33, 34). While vanadium compounds are potentially mitogenic and are reported to exert tumorigenic/carcinogenic activity, more recent studies suggest anti-mitogenic and anti-tumor activity of certain vanadium compounds (35–39).
Inorganic Chemical Pollutants

In industry, chlorine comes from rock salt (NaCl). Chlorine is then used in drinking water and in a variety of industrial practices for the production of chlorinated solvents, for example, CCl4, CCl3, trichloroethane, plastics, and vinyl chlorides, etc. Mild mucous membrane irritation may occur at 0.2–16 ppm; eye irritation occurs at 7–8 ppm, throat irritation at 15 ppm, and cough at 30 ppm.881 In several cases, prolonged symptoms following chlorine exposure may have been caused by aggravation of preexisting conditions, such as tuberculosis or heart disease.882 Higher concentrations can cause severe poisoning in even shorter periods.883 Chlorine dioxide also causes similar respiratory ailments.883 Lower levels of chlorine concentrations can cause irritation of the lower respiratory passages, the eyes, the nose, and the throat. Excess chlorine may put a strain on the dehalogen oxidation and conjugation systems.
Response from the National Governments

Traditionally, IAQ has been associated with Sick Building Syndrome (SBS). The World Health Organization (WHO) compiled common reported symptoms into what was defined as SBS. These symptoms included: eye, nose, and throat irritation; sensation of dry mucous membranes; dry, itching, and red skin; headaches and mental fatigue; high frequency of airway infections and cough; hoarseness and wheezing; nausea and dizziness; and unspecific hypersensitivity. Most of us are facing these problems today and frequently so. We have to keep visiting doctors and chemists.
Analysis of roadside air pollutant concentrations and potential health risk of exposure in Hanoi, Vietnam
Published in Journal of Environmental Science and Health, Part A, 2020
Van Tai Tang, Nguyen Thi Kim Oanh, Eldon R. Rene, Tran Ngoc Binh
From a health risk point of view, persons working on the roadside (including street hawkers) are directly exposed to polluted air for the entire working time, but the percentage of face mask users among them was the lowest. On the other hand, the pedestrians and motorcycle drivers are usually exposed to roadside air pollutants for the time they are commuting in the streets but they had high percentages of face mask users. This precautionary attitude would reduce the effect of PM inhalation among the motorcycle drivers.[11,37] Higher percentage of people using facemasks during rush-hour, i.e. when compared with non-rush hours, the average ratio of using face mask by motorcycle drivers, pedestrians and workers during rush hour was ∼ 1.4, 1.9 and 1.2 times higher, respectively. In the future, field surveys should include a large group of motorcycle riders, pedestrians and workers who wear facemask and those who do not wear facemask. The results of such surveys can be used to comparatively analyze the health symptoms such as headache, dizziness, tiredness, sickness, cough, difficulty in breathing, irritation of the eyes, irritation of the throat, irritation of the nose, unpleasant smell, bad taste, difficulty in walking, etc., between the two groups on both the short term and long term exposure periods.
Measurements and health impacts of carbon black and BTEXs in photocopy centers
Published in Archives of Environmental & Occupational Health, 2018
Pattama Senthong, Sivasit Wittayasilp
The health symptoms occurring during copying service among workers are consistent with the earlier reports where inhalation of carbon black can cause cough, headache, and nose and throat irritation. Skin contact with carbon black can cause eye and skin irritation.32 Additionally, toluene exposure can also can cause coughing, sore throat, dizziness and headaches.33 Photocopy center A is located in the basement and in the corner that lead to a confined space. Although the average concentration of carbon black and toluene were below the permissible exposure limit and threshold limit value. Local exhaust ventilation in photocopy center as well as personal protective equipment are strongly recommended during operation hours to prevent or minimize work related symptoms and illnesses.
An evaluation of occupant health and indoor environmental quality in university workspaces
Published in Human and Ecological Risk Assessment: An International Journal, 2023
Health symptoms consisted of 22 questions categorized into four different groups of symptoms (mucosal, dermal, psychological, and general symptoms). Mucosal symptoms included eye irritation, dryness and itching, blurred vision, runny and stuffy nose, nose irritation and itching, cough and sore throat, throat irritation, and asthma. Dermal symptoms included itching in the skin or the face and dry skin. Psychological symptoms included difficulty in concentration, tension or stress, depression, and aggression. At last, general symptoms included heart palpitations and pain, blood pressure, headache, nausea, dizziness, pain in shoulder, neck or back muscles, fatigue, or lethargy, feeling drowsy and insomnia, and sleep disorder.
