Transfer of Organochlorine Pesticide Residues into Cigarette Smoke as a Function of Tobacco Blends and Filter Types

Abstract

The transfer during smoking of pesticides contained in tobacco into the smoke and the filter of cigarettes was investigated. The overall transfer into the mainstream smoke was 17 %. It was found to be independent of the type of the tobacco blend (American, Maryland, Virginia and Oriental). The pesticide retention of the following four filters was investigated: cellulose filter, cellulose acetate filter with low and high pressure drop, and a charcoal filter, characterized by nicotine retentions of 38 %, 27 %, 48 % and 54 %, respectively. The corresponding pesticide retentions found were 40 %, 21 %, 39 % and 38 %, i.e. lower than the nicotine retention in the cellulose acetate, and significantly lower in the charcoal filter. A 3 % degradation of p,p'-DDT and o,p'-DDT contained in tobacco to p,p'-DDE and o,p'-DDE respectively, was also observed. The pesticides initially contained in the tobacco part of the cigarette butt decreased during smoking. This appears to be the result of some initial condensation of substances carried through by the smoke stream (as indicated by the presence of pesticide degradation products), followed by strong desorption during the very last puffs.

Waterborne Toxicity to Neotropical Invertebrates and Hazard of Cigarette Butt Leachates in Marine Environments

“…However, we considered the additive effects of the substances present in the samples. In this sense, the chemical profile of the leachate was analyzed as a proxy for chemicals released from CBs because it is difficult to quantify all classes of contaminants In addition to trace metals and hydrocarbons, the particulate phase of smoked cigarettes retained in the filter can contain more than 3500 individual components, including pesticides, nicotine, nicotiana alkaloids, catechols, and products related to Solanaceae (Ceschini & Chauchaix, 1980; Kurmus & Mohajerani, 2020; Mussalo‐Rauhamaa et al, 1986).…”

Optimization and validation of ultrasound application with a low-temperature method to analyze organochlorine pesticides in smuggled cigarette tobacco

“…This process may generate other potentially harmful compounds to human health, as shown by studies that detected OCPs such as DDT, DDE, aldrin, dieldrin, endrin, endosulfan, and BHCs in smoke and lters, which were not detected in cigarette ash. [45][46][47][48][49] Dane, Havey, and Voorhees 50 compared the concentrations in tobacco and smoke and concluded that approximately 10% of the compounds were volatilized, and the remainder was thermally degraded during combustion.…”
