Abstract: Experimental studies were performed on healthy, 80-100 g carp (Cyprinus carpio). Fish were exposed by emersion in Roundup (205 mg of glyphosate/l or 410 mg of glyphosate/l) in concentrations of 40- to 20-fold lower than those used in practice. Electron microscopy revealed that the herbicide caused appearance of myelin-like structures in carp hepatocytes, swelling …
Abstract: This study was conducted on fingerlings of carp. Cyprinus carpio L., that were either clinically healthy or infected with a natural invasion of the ciliate, Ichthyophthirius multifiliis. The fish were exposed for 96 h to Avans 330 SL in a concentration of 2 mg trimethylosulfonium glyphosate l-1 water in order to establish its effect …
Abstract: Transport of lawn-applied herbicides into the home via walking over treated turf, defined here as track-in, was measured at five different times out to 1 week after application. Residues of turf-applied 2,4-D and dicamba were measured in carpet dust and on the carpet surface after track-in. Both carpet dust levels and carpet surface dislodgeable residue …
Abstract: Fish proteins occupy an important place in human nutrition. They are well balanced with essential amino acids and are comparable to other proteins of animal origin. Moreover, carbohydrate content of the fish flesh is very low. Considering their nutritional value, it is essential for any nation, which is desirous of developing this rich protein …
Abstract: Improvements in the performance of fish species used in aquaculture are being accomplished using a variety of approaches, including both traditional and molecular genetic methodologies. Historical gains in productivity have been achieved by domestication, selection, interspecific and interstrain crossbreeding, polyploidy, and synthesis of monosex populations. More recently, transgenesis has been explored as a technique …
Abstract: The objective of this study was to investigate the toxicity effects of acute and sublethal of Roundup® as a glyphosate-based herbicide on acetylcholinesterase (AChE) activity and several hematological and biochemical parameters of Cyprinus carpio. The LC50-96 h of Roundup® to C. carpio was found to be 22.19 ppm. Common carp was subjected to Roundup® …
Abstract: The effects of sublethal concentrations of Roundup [glyphosate] (4, 6, 8 mg/litre) in water on non-specific immunity and the liver and kidneys was investigated in 120 healthy carp weighing 60-80 g. Non-specific immunity, phagocytic activity of blood and kidney neutrophils and macrophages, and lysozyme level all decreased during the experiment. Histopathology revealed degenerative changes …
Abstract: Rural residents can be exposed to agricultural pesticides through the proximity of their homes to crop fields. Previously, we developed a method to create historical crop maps using a geographic information system. The aim of the present study was to determine whether crop maps are useful for predicting levels of crop herbicides in carpet …
Abstract: Transport of lawn-applied 2,4-D into 13 actual homes was measured following both homeowner and commercial application of this herbicide to residential lawns. Collection of floor dust in five rooms of each house, corresponding to an entryway, living room, dining room, kitchen, and a child’s bedroom, both prior to and after application, indicated that turf …
Abstract: In this study, we investigated the 2,4-dichlorophenoxyacetic acid (2,4-D) herbicide exposures of 135 preschool-aged children and their adult caregivers at 135 homes in North Carolina (NC) and Ohio (OH). Participants were randomly recruited from six NC and six OH counties. Monitoring was performed over a 48-h period at the participants’ homes. Environmental samples included …
Abstract: The aim of this study was to assess the use of pesticides on farms located in the Lambedor River watershed in Guatambu, State of Santa Catarina, as well as to determine, by micronucleus testing, the risk of genotoxic impact. Samples from locally collected Cyprinus carpio, Hypostomus punctatus, Rhamdia quelen and Oreochromis niloticus gave evidence …
Abstract: A few days ago, Trevor Charles posted a review of our paper entitled “The Precautionary Principle (with Application to the Genetic Modification of Organisms).” Here we provide a response. Keywords: Precautionary Principle, Carpenter Fallacy, Probability, Biology, Systems Engineering Citation: Taleb, N.N., Read, R., Douady, R., Norman, J., and Bar-Yam, Y., 2014, November 28. Response …
Abstract: The effects of potential risk factors for Hodgkin’s disease (HD) and for non-Hodgkin lymphomas (NHL) were evaluated in a case-referent study encompassing 54 cases of HD, 106 cases of NHL, and 275 referents, all alive. Exposure information was obtained by questionnaires posted to the subjects. Crude rate ratios were increased for various occupational exposures …
Text: We agree with Obrycki et al. (2001) that a broad-based ecological approach for new pest management technologies is desirable, but we unanimously and strongly disagree with some of their assumptions and conclusions about Bt corn. Bt corn is corn that has been genetically engineered to produce insecticidal proteins from the bacterium Bacillus thuringiensis. Because …
Introduction: Human society relies on surface freshwater ecosystems for many goods and services (drinking water, recreational facilities…), which places these systems at the center of a web of ecological, economic and political interests (Wilson & Carpenter, 1999). They are also being subjected to increasing pressure resulting from anthropogenic activities, including contamination by a variety of …
Abstract: The Swedish Cancer Environment Register (CER) is a linkage of census data (e.g., on occupations) with the Swedish Cancer Register. It has been used in different studies to generate hypotheses on occupational risk factors for malignant tumors. In this study the risk for malignant lymphoma and multiple myeloma in occupations with potential exposure to …
Abstract: A bacterial phytoene synthase (crtB) gene was overexpressed in a seed‐specific manner and the protein product targeted to the plastid in Brassica napus (canola). The resultant embryos from these transgenic plants were visibly orange and the mature seed contained up to a 50‐fold increase in carotenoids. The predominant carotenoids accumulating in the seeds of the …
