The distribution of nine pesticides between the juice and pulp of carrots and tomatoes during home culinary practices was investigated. Tomato and carrot pulp contained a higher percentage of all pesticide residues, except for mancozeb in tomatoes. Although there was a difference in the relative distribution of the pesticides between the commodities with greater amounts present in the pulp of tomatoes, the pesticides followed a similar trend in both. A relationship between the pulp/juice distribution and water solubility of the pesticide was apparent. Pesticides with the highest water solubility were present to a greater extent in the juice. An exception was noted in the case of diazinon and parathion, which were present in higher amounts in the pulp than their water solubility would suggest. The percent residue in the pulp ranged from 56.4 to 75.2% for carrots, and 49.7 to 95.4% for tomatoes. Residues in the juice prepared from washed commodities ranged from not detected to 0.83 microgram/g. Washing of the produce removed more residue from carrots than from tomatoes, but it did not affect the relative distribution of the residues. The behaviour and fate of the chemical varied with the pesticide as well as the crop.
研究了九种农药在家庭烹饪过程中在胡萝卜和番茄的果汁和果肉之间的分布情况。除了番茄中的代森锰锌外，番茄和胡萝卜的果肉中所有农药残留的百分比都更高。尽管在这两种商品中，农药在果肉中的相对分布存在差异，且番茄果肉中的农药含量更高，但两种商品中的农药都呈现出相似的趋势。农药的果肉/果汁分布与水溶性之间存在明显的关系。水溶性最高的农药在果汁中的含量更高。但二嗪农和对硫磷是例外，它们在果肉中的含量高于其水溶性所对应的含量。胡萝卜果肉中的残留百分比在56.4%至75.2%之间，番茄果肉中的残留百分比在49.7%至95.4%之间。用清洗后的商品制备的果汁中的残留量从未检出到0.83微克/克不等。清洗农产品后，胡萝卜去除的残留量比番茄多，但这并不影响残留的相对分布。化学物质的行为和归宿因农药和作物而异。
