What pesticides are used in MEKC?
Eight widely used fungicides namely carbendazim, imazalil, methylthiophanate, o-phenylphenol, procymidone, prochloraz, triamidefon and thiabendazole were separated with BGE containing borate buffer at pH 9 and 75 mmol/L sodium cholate as surfactant [ 75 ]. The applicability have been shown through spiked food extracts from grape, tomato, lettuce and orange as shown in Figure 11 [ 75 ]. Sample stacking have been developed increasing the sensitivity of the MEKC method and successfully applied for non-spiked apple juice [ 76 ]. The separation electrolyte contained 10 mmol/L phosphate as buffer, 30 mmol/L SDS and isopropanol / isobutylalcohol function as organic modifier enhancing the selectivity of the separation. The sample stacking was achieved by salting the injected sample. Pre-concentration strategies like sweeping, stacking and modified staking with combination of MEKC have been studied for nine multiple pesticides determined from spiked carrot samples because the most problematic task in the CE analysis of food contaminant is the sensitivity of a method [ 14, 77 ]. Atrazine, a triazine type pesticide, have been determined by MEKC from juices with combination of supported liquid membrane and solid-phase extraction used for sample preparation to increase the selectivity and sensitivity of the analytical process [ 78 ].
What is the best method to separate pesticide residues?
Micellar electrokinetic chromatography (MEKC) and capillary electrochromatography (CEC) are powerful techniques for achieving efficient pesticide and pesticide residue separations, although accepted standardized methods are still missing. The N -methylcarbamates, carbendazin, imazalil, methylthiophanate, prochloraz, procimidone, thiabendazole, triadimefon, metribuzin, lenacil, ethofumesate, atrazine, terbuthrin, isoproturon, chlorotoluron, linuron, desethyl atrazine, 2-hydroxyatrazine, desethyl 2-hydroxyatrazine, and 3-chloro-4-methylphenyl urea are only some of the pesticides that have been reported to be separated by means of MEKC and CEC. Online coupling of MEKC with ESI-MS was recently found as achievable using partial filling (PF) or reverse migrating micelles (RMM) techniques. Quantitative migration–toxicity relationship for phenoxy acid herbicides has been obtained with MEKC on using micellar Brij 35 based migration media. Online stacking procedure carried out on injection acts as a preconcentration step and together with SPE for sample preparation shifts the detection limits to the low μg l −1 range, even on use of the classical on-column diode array detection.

Is methyl thiophanate toxic to animals?
The fungicide methyl thiophanate widely used to control some of the most common fungal diseases in crops is metabolized in animals into benzimidazole compounds, including the reproductive toxicant carbendazim. However, standard toxicological tests did not indicate that methyl thiophanate may cause testicular toxicity and/or embryotoxicity, which are typical effects of many benzimidazoles. In the B6C3F1 mouse in spite of the high doses administered, none of the testicular parameters examined (sperm head count, specific enzyme activities, histopathology on days 3–35 post-dosing) showed significant alterations as compared to controls at any time post-dosing. Pregnant CD rat dams administered orally the limit dose of 650 mg/kg BW/day during preimplantation (gestational day or GD 2–5) or peri-implantation (GD 6–9) phases showed maternal toxicity, with only marginal reductions of the growth of embryos and adnexa ( Traina et al., 1998 ). Earlier studies submitted by Atochem North America, Inc. (1985) for methyl thiophanate, show for the rat a teratogenic NOAEL = 2500 ppm (125 mg/kg/day) based on the high dose tested (HDT) with a maternal NOAEL = 250 ppm (12.5 mg/kg/day), LEL = 1200 ppm (60 mg/kg/day) and a fetotoxic NOAEL = 2500 ppm (HDT).

How long does it take for thiophanate methyl to degrade?
Thiophanate-methyl degraded by 90% during a 6-18 week period in soils of various textures, suggesting that biodegradation may be a moderate environmental fate process in soil.

How long does thiophanate methyl stay in the atmosphere?
Vapor-phase thiophanate methyl will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 5 hours. Particulate-phase thiophanate methyl will be removed from the atmosphere by wet or dry deposition.
What are the symptoms of exposure to a compound?
SYMPTOMS: Symptoms of exposure to this compound may include irritation, itching, redness, swelling, and dryness of the skin; congestion; and, sometimes, dermatitis. ACUTE/CHRONIC HAZARDS: This compound may irritate the skin. When heated to decomposition it emits very toxic fumes of NOx and SOx. (NTP, 1992)
How does thiophanate methyl release to the environment?
Thiophanate methyl's production may result in its release to the environment through various waste streams; its use as a fungicide will result in its direct release to the environment. If released to air, a vapor pressure of 7.13X10-8 mm Hg at 25 °C indicates thiophanate methyl will exist in both the vapor and particulate phases in the atmosphere. Vapor-phase thiophanate methyl will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 5 hours. Particulate-phase thiophanate methyl will be removed from the atmosphere by wet or dry deposition. Thiophanate-methyl is stable to sunlight, suggesting that the compound is not expected to be susceptible to direct photolysis in sunlight. If released to soil, thiophanate methyl is expected to have moderate mobility based upon an estimated Koc of 330. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 1.2X10-9 atm-cu m/mole. Thiophanate methyl will not volatilize from dry soil surfaces based upon its vapor pressure. Thiophanate-methyl degraded by 90% during a 6-18 week period in soils of various textures, suggesting that biodegradation may be a moderate environmental fate process in soil. If released into water, thiophanate methyl is expected to adsorb to suspended solids and sediment based upon the estimated Koc. Thiophanate-methyl was degraded in aqueous solution by irradiation with UV and sunlight to methyl benzimidazole-2-yl carbamate. Biodegradation data in aquatic media were not available. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 4 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound is stable in neutral, aqueous solution; however it may be reactive under basic conditions. Occupational exposure to thiophanate methyl may occur through inhalation and dermal contact with this compound at workplaces where thiophanate methyl is produced or used. Use data indicate that the general public may be exposed to thiophanate methyl via inhalation and dermal contact with consumer products containing this compound. (SRC)
