“…Doporučované limitní hodnoty jsou podle WHO [3] pro kyselinu dichloroctovou 50 µg/l a pro kyselinu trichloroctovou 100 µg/l. V některých státech již byla provedena screeningová měření a zjišťována frekvence výskytu těchto vedlejších produktů chlorace v pitných vodách sloužících k zásobování obyvatelstva [19][20][21]. Dále jsou v chlorovaných pitných vodách nebo při modelových pokusech s chlorací vodných roztoků humátů nacházeny další nižší alifatické chlorované kyseliny [22], bromované halooctové kyseliny [23], chlorovaný a bromovaný acetonitril [15], chlorované aldehydy a ketony [17], zvláště pak chlorovaný acetaldehyd [17], popřípadě do různého stupně bromovaný acetaldehyd [24] a chlorkyan [25] (ten se tvoří pře-devším za přítomnosti vyšších koncentrací amonných iontů, resp.…”

“…Limits recommended by World Health Organization [3] are 50 µg/l for dichloroacetic acid and 100 µg/l for trichloroacetic acid, respectively. In several countries [19][20][21] reconnaissance surveys were performed for concentration of haloacetic acids in drinking waters. Haloacetic acids are not easily removed from water at higher temperature due to their higher polarity.…”

“…This family of compounds includes important intermediates in the degradation of other chlorinated solvents. DCAA and TCAA are important byproducts from drinking water disinfection with chlorine (Peters et al 1991;Hu et al 1999). They are also significant secondary atmospheric pollutants formed from the oxidation of atmospheric PCE and 1,1,1-TCA or natural compounds formed during oxidation of humic substances ( Table 17.…”

The biodegradability of chlorinated methanes, chlorinated ethanes, chlorinated ethenes, chlorofluorocarbons (CFCs), chlorinated acetic acids, chlorinated propanoids and chlorinated butadienes was evaluated based on literature data. Evidence for the biodegradation of compounds in all of the compound categories evaluated has been reported. A broad range of chlorinated aliphatic structures are susceptible to biodegradation under a variety of physiological and redox conditions. Microbial biodegradation of a wide variety of chlorinated aliphatic compounds was shown to occur under five physiological conditions. However, any given physiological condition could only act upon a subset of the chlorinated compounds. Firstly, chlorinated compounds are used as an electron donor and carbon source under aerobic conditions. Secondly, chlorinated compounds are cometabolized under aerobic conditions while the microorganisms are growing (or otherwise already have grown) on another primary substrate. Thirdly, chlorinated compounds are also degraded under anaerobic conditions in which they are utilized as an electron donor and carbon source. Fourthly, chlorinated compounds can serve as an electron acceptor to support respiration of anaerobic microorganisms utilizing simple electron donating substrates. Lastly chlorinated compounds are subject to anaerobic cometabolism becoming biotransformed while the microorganisms grow on other primary substrate or electron acceptor. The literature survey demonstrates that, in many cases, chlorinated compounds are completely mineralised to benign end products. Additionally, biodegradation can occur rapidly. Growth rates exceeding 1 d )1 were observed for many compounds. Most compound categories include chlorinated structures that are used to support microbial growth. Growth can be due to the use of the chlorinated compound as an electron donor or alternatively to the use of the chlorinated compound as an electron acceptor (halorespiration). Biodegradation linked to growth is important, since under such conditions, rates of degradation will increase as the microbial population (biocatalyst) increases. Combinations of redox conditions are favorable for the biodegradation of highly chlorinated structures that are recalcitrant to degradation under aerobic conditions. However, under anaerobic conditions, highly chlorinated structures are partially dehalogenated to lower chlorinated counterparts. The lower chlorinated compounds are subsequently more readily mineralized under aerobic conditions.Abbreviations: A

“…In the presence of bromide ion (Br-), more brominated and mixed chloro-bromo derivatives are formed (Krasner et al, 1989;Peters et al, 1991;Heller-Grossman et al, 1993;Pourmoghaddas and Stevens, 1995). This is the result of bromide oxidation to hypobromous acid (HOBr) by chlorine and the reaction of HOBr and residual HOCl with NOM.…”

<p>Chlorination of drinking water leads to the formation of a variety of Disinfection By-Products (DBPs) that may have adverse health effects on humans. Research on this subject has been continued and new epidemiological and toxicological studies have been conducted. This review summarizes factors affecting DBP formation and predictive equations proposed for it, physical and chemical properties, environmental fate, actual measurements of these compounds and technologies for controlling them, as well as regulation and currently proposed changes of their Maximum Contaminant Levels (MCLs) after evaluation by EPA of new data available.</p>
