“…Logical candidates for study are those recognized as having class 3 (reactive) or class 4 (specific mechanism reactivity) aquatic toxicity and/or the potential risk of developmental and reproductive toxicity and genotoxicity (Table ). To that list, pesticides such as the once-banned paraquat and the controversial glyphosate (and metabolite AMPA) are among those of concern in recent studies in Thailand, as well as selected organophosphates, carbamates, and pyrethroids of recent investigations. ,,, …”

“…Thus, the new data on atrazine concentrations from our study enable a longitudinal assessment of the importance of this pesticide, allowing for exploration of persistence across a calendar year. Finally, few studies in the country have been able to assess the diversity of pesticides detectable in environmental systems, with most typically focusing on a few selected entities or groups of pesticides. − These types of information, although piecemeal in time, have rarely been performed in Thailand and other Southeast Asian countries.…”

This study investigates the longitudinal and temporal trends of atrazine, a persistent herbicide, in the Mae Sa catchment in northern Thailand. Concentrations of atrazine determined from targeted analysis were elevated during the wet season, and great variability was observed in relation to individual storm runoff hydrographs. When compared to regulatory limits, the observed atrazine concentrations in Mae Sa were generally below environmental thresholds of concern. However, greater risk may occur in other tributary systems feeding the Ping River, where some concentrations exceeding 2000 ng/L were observed, although they were not sustained for extended periods of time. Additionally, nontargeted screening identified 16 other agrochemicals with known potential environmental risks or associated toxicity. Despite the minor risk posed by atrazine alone, the research highlights the intricate interplay of agricultural practices, diverse pesticide application, and hydroclimatic factors in influencing pesticide dynamics. In the broader context, this study underscores the challenge of estimating risks arising from pesticide mixtures while using a combination of targeted analysis, nontargeted screening, in silico prediction models, and in vitro bioassays. Collectively, we find evidence of the presence of more than 100 pesticides in the catchment since dedicated work began there more than a decade ago.

“…According to a previous report by Klaimala et al . [ 32 ] concerning pesticide residues in Thailand, fipronil was widely used for home termite, ant, and cockroach control, and it was one of the most common residues on home surfaces and children’s hands in one study. The rise in product availability and lower price of generic formulations of fipronil could lead to increased pet exposure to fipronil because patent protection for this drug ended in August 2010 [ 5 , 33 ].…”

Background and Aim: Administration is the main strategy for controlling ectoparasites in dogs. Ivermectin and fipronil are most extensively used to prevent and treat Rhipicephalus sanguineus sensu lato infestation in dogs in Thailand. Several researchers have reported resistance to acaricides in R. sanguineus s.l. globally, but documentation of acaricide resistance in the tick population in Thailand is lacking. In this study, we investigated the status of resistance to commonly used acaricides in Thailand in R. sanguineus s.l. Materials and Methods: Engorged brown dog tick females (10 tick populations) were field-collected directly from parasitized dogs in Maha Sarakham, Thailand, for toxicological bioassays with ivermectin and fipronil. Bioassays were performed in three replicates at 25°C-27°C and 80%-85% relative humidity under a 12-h/12-h photoperiod. The 50% of lethal concentration and its confidence intervals and the slope were estimated for each tick population using probit analysis. Resistance ratios (RRs) of field ticks were characterized based on the relative susceptible population of each acaricide. Results: Six tick populations (P1-6) were tested for resistance to ivermectin, three of which (P2-4) exhibited low-level resistance to ivermectin (RR = 2.115-2.176). Of four tick populations (P7-10) treated with fipronil, two exhibited moderate-to-severe resistance (P7 and P9, RR = 21.684 and 4.387, respectively). All tick populations deemed resistant to acaricides had a history of exposure. Conclusion: Based on RR values, four R. sanguineus s.l. tick populations from Maha Sarakham province were resistant to ivermectin and fipronil. To the best of our knowledge, this represents the first documentation of acaricide-resistant populations of R. sanguineus s.l. in Thailand, and recommendations on tick control programs must be formulated with veterinarians and pet owners to prevent the development of further resistance. Keywords: bioassay, dog, fipronil, ivermectin, resistance, Rhipicephalus sanguineus sensu lato, Thailand.

“…Additionally, the Environmental Protection Agency (EPA) has shown that in the rural Yakima Valley, Washington, up to 87 pesticides were detected in household dust samples, 47 of which have neurotoxic potential. On the other hand, in Thailand, fipronil, parathion, and chlorpyrifos were found in residential dust [ 4 , 11 ]. These data indicate that an average person is indirectly exposed with pesticides daily.…”

Pesticides are chemical substances used to control, prevent, or destroy agricultural, domestic, and livestock pests. These compounds produce adverse changes in health, and they have been associated with the development of multiple chronic diseases. This study aimed to present a detailed review of the effect of pesticides on the oral cavity and the oral microbiome. In the oral cavity, pesticides alter and/or modify tissues and the microbiome, thereby triggering imbalance in the ecosystem, generating an inflammatory response, and activating hydrolytic enzymes. In particular, the imbalance in the oral microbiome creates a dysbiosis that modifies the number, composition, and/or functions of the constituent microorganisms and the local response of the host. Pesticide exposure alters epithelial cells, and oral microbiota, and disrupts the homeostasis of the oral environment. The presence of pesticides in the oral cavity predisposes the appearance of pathologies such as caries, periodontal diseases, oral cancer, and odontogenic infections. In this study, we analyzed the effect of organochlorines, organophosphates, pyrethroids, carbamates, bipyridyls, and triazineson oral cavity health and ecosystems.
