Notes: Abstract This study addresses the measurements of glyphosate exposure received by 14 workers employed at two tree nurseries. The applicators, weeders, and scouts monitored all wore normal work clothing, which for applicators was a protective suit, rubber gloves and boots. Measurements were made of the glyphosate that was dislodged from conifer seedlings during water rinses taken twice weekly from May through August. Only 1 of these 78 dislodgeable residue samples were positive for glyphosate. Nine cotton gauze patches were attached to the clothing of each worker one day per week during this same period. Hand washes were taken on the same day that patches were worn. Most patches and hand washes from applicators and weeders contained measurable amounts of glyphosate. Analyses of individual patches showed that the body portions receiving the highest exposure were ankles and thighs. For scouts only 1 of 23 hand washes contained glyphosate. To provide a measure of the exposure occurring via all exposure routes (dermal, ingestion, and inhalation) an analysis was made of the total urine excreted. For most workers a daily total urine collection was made for 12 consecutive weeks. Urine analysis, the biological monitoring tool used to assess the total amount absorbed via all avenues, did not reveal any positive samples. The lower limit of method validation for glyphosate in the urine samples was 0.01 μg/ml. High rainfall, or irrigation as needed, in conjunction with normal field dissipation avenues and worker training were cited as contributing factors for the low amounts of glyphosate exposure found. None of the exposure parameters indicated that glyphosate exposure poses a threat to human health when used under normal nursery conditions.

Notes: Use of silane coupling agents enables the significant improvement of the performance of thermoplastic composites. Water-borne silane coupling agents may offer a more environmentally friendly alternative. Compositions of nylon 66 with silane and water-borne silane treated mineral fillers: clay, talc, mica and wollastonite were prepared and comparatively evaluated. Filler dispersion, mechanical properties, and thermoplastic matrix-mineral substrate interface were studied. It may be gathered from the results of the study that water-borne silanes by themselves or in combination with some additives exhibit equal or better performance than regular silanes.
