Abstract: Because pesticides are ubiquitous and focused on the food chain, they are a substantial source of possible environmental danger to humans and animals. The highest extremely hazardous herbicides to be launched in 60 years ago is paraquat (1,1'-dimethyl-4,4'-bipyridylium dichloride). Although most nations have prohibited or severely limited the use of paraquat (PQ), it is still used in others, particularly in Nigeria. As a result, the present study used a spectrophotometric method to look for PQ in some vegetables, crops, and fruits in Abeokuta that are commonly consumed. The presence and amounts of PQ residues were assessed in 150 samples of various vegetables, crops, and fruits (harvested at Fadama field of the University of Agriculture, Abeokuta). PQ residues were detected in Talinum triangulare, Corchorus olitorius, Amaranthus caudatus, Cratylia argentea, Capsicum frutescens, Lycopersicum esculentum, Raphanus sativus, Zea may, and Dioscorea alata at 0.130.02, 0.27+0.02, 0.06+0.01, 0.10+0.03, 0.15+0.03, 0. Using this technique, no paraquat residues were found in M. paradisicica or C. papaya. At 0.05-1.0 ppm fortification level, the technique yields a mean recovery of over 80% and is reproducible with a total coefficient of variation of 8.0 percent (n=10). All residual levels found were under the PQ tolerance or pesticide maximum limits.

Metabótitos secundários produzidos em algumas plantas podem provocar alterações no desenvolvimento de outras plantas ou até mesmo de outros organismos. Neste trabalho, objetivou-se identificar possíveis efeitos alelopáticos de extratos aquosos de folhas de Cyperus rotundus na germinação e no crescimento de plântulas de Brassica campestris, Brassica oleracea var. botrytis, Brassica oleracea var. capitata, Brassica oleracea var. italica, Brassica rapa, Lactuca sativa cv. Grand rapids, Lycopersicum esculentum e Raphanus sativus. Foram utilizadas sete concentrações do extrato aquoso (0, 10, 30, 50, 70, 90 e 100%). Os tratamentos foram arranjados em delineamento inteiramente casualizado, com cinco repetições de dez sementes das espécies cultivadas, constituindo a unidade amostral. Os extratos aquosos de C. rotundus evidenciaram potencialidades alelopáticas na germinação das sementes e no crescimento das duas partes vegetais (raiz e parte aérea), de todas as espécies testadas, exceto na germinação de sementes de tomate e de alface, sendo que a redução aumentou com o aumento das concentrações dos extratos aquosos utilizados. A estrutura vegetal mais afetada em presença dos extratos aquosos foi o sistema radicular das plântulas.

Fish-Chili- sauce processed by a mixture of cayenne pepper (Capsicum frutescens), tomatoes (Lycopersicum esculentum) and Deles fly fish (Decapterus macrosoma) as fast-food sources of protein that is favored by the public. The purpose of this study are to determine the protein and vitamin C levels of fish-chili-sauce before and after processing. The research method are used completely randomized design with two treatments, namely treatment 1 measured levels of protein and vitamin C before processing; treatment 2 measures the levels of protein and vitamin C after processing. The protein test was performed using the Kjeldahl method with a Spectrophotometer Technique. Vitamin C testing uses the Iodimetry method. The results showed that protein levels of fish before processing = 19.31% and = 20.24 mg/100g of vitamin C. After processing the fish protein content  = 15.63% and = 16.28 mg/100g of vitamin C levels. Decreased fish protein levels and vitamin C levels were thought to be due to the length of processing time. The results of the analysis of the T-Test Pairs showed that there are no significant difference in the protein content of fish-chili-sauce before and after processing, but it tended to decrease. The results of the analysis of the Pairs T-Test showed that there are significant differences in the levels of vitamin C of fish-chili-sauce before and after processing.ABSTRAKSambal-ikan hasil olahan campuran cabai rawit (Capsicum frutescens), tomat (Lycopersicum esculentum) dan ikan layang Deles (Decapterus macrosoma) sebagai sumber protein cepat saji yang digemari oleh masyarakat. Tujuan penelitian ini untuk mengetahui kadar protein dan vitamin C sambal-ikan sebelum dan sesudah diolah. Metode penelitian di gunakan Rancangan Acak Lengkap dengan 2 perlakuan yaitu perlakuan 1 mengukur kadar protein dan vitamin C sebelum diolah; perlakuan 2 kadar protein dan vitamin C sesudah diolah. Uji protein dilakukan menggunakan metode Kjeldahl dengan Teknik Spektrofotometer. Uji vitamin C menggunakan metode Iodimetri. Hasil penelitian menunjukkan kadar protein 19,31% dan kadar vitamin C 20,24 mg/100g. 15,63%. dan kadar vitamin C16,28 mg/100g. Penurunan kadar protein ikan dan kadar vitamin C diduga karena lamanya waktu proses pengolahan. Hasil analisi uji T-Test Pairs menunjukkan tidak ada perbedaan yang signifikan pada kadar protein sambal-ikan sebelum dan sesudah diolah, namun cenderung mengalami penurunan. Hasil analisis uji T-Test Pairs menunjukkan ada perbedaan yang signifikan pada kadar vitamin C sambal-ikan sebelum dan sesudah diolah.

Stranding is the event in which a marine animal comes ashore after death or comes and is unable to return to the sea, which may occur due to natural, spatial tendencies and anthropic actions. It occurs in many countries, several of which have created formal programs to monitor. Mammals are at the top of the food chain, suffering more from changes in the environment, which is why they indicate the quality of the ecosystem. In the southern region of Brazil, inventories of marine mammal biodiversity emerged in the 1980s. Registering stranded data makes it possible to discover important information about marine animals and the oceans. This work aimed to collect information to identify the composition and abundance of strandings of marine mammals. The studied area is located on the southern coast of Santa Catarina, between the municipality of Jaguaruna and Passo de Torres. Data refer to collections made by the Zoology Museum Morgana Cirimbelli Gaidzinski , from the University of the Extreme South of Santa Catarina (UNESC), during the period from 2003 to 2016, through third-party activations and systematic monthly monitoring. The stranding frequency in this period was 344 mammals, belonging to 15 species, 10 genera, six families and two different orders. The occurrence of rare and unpublished animals was observed, such as Balaenoptera physalus, Kogia breviceps and Arctocephalus gazela.

Por pruebas de invernadero y laboratorio se estudió la variabilidad patogénica de nueve poblaciones de Nacobbus aberrans provenientes de diferentes localidades de Argentina, Bolivia, Ecuador y Perú. Las susceptibilidades de las especies de plantas se evaluaron por la presencia o ausencia de nódulos y/o los diferentes estados de desarrollo de N. aberrans presentes en sus raíces. Luego de seleccionar Solanum tuberosum ssp. andigena, Lycopersicum esculentum, Beta vulgaris y Capsicum frutescens como plantas diferenciales, se estableció la existencia de cinco poblaciones patogénicamente diferentes o razas. De estas cinco razas, tres estarían presentes en Bolivia.Por otro lado, se determinó como hospedantes de N. aberrans a veinte especies vegetales entre plantas cultivadas y no cultivadas, colectadas en campos agrícolas de la Estación Experimental de Toralapa y sus alrededores (Cochabamba, Bolivia). Asimismo ocho especies se mostraron como posibles hospedantes por la presencia de J2, J3 y J4 en sus raíces no así trece especies que se comportaron como no hospedantes.Aceptado para publicación: setiembre 1998.

ABSTRACTChemical content of crops above desirable level, high cost, in addition to land and water pollution is a major drawback of applying chemical fertilizers. In this study, Digestate was used as a biofertilizer for the growth of selected vegetables. Furthermore, Illumina platform was employed to unravel the bacteria community of the digestate. Corchorus olitorius, Amaranthus hybridus, Bot-celosia argentia and Talinum triangulare were grown in 16 experimental pots for 35days using cured digestate. Soil treated with chemical fertilizer was used as a positive control while the soil without any fertilizer was used as a negative control. The plant height of Talinum triangulare for soil treated with digestate was 23.5cm and 34cm by days 7 and 35 respectively after plant emergence. Corchorus olitorius had stunted growth under same treatment. Whereas, Bot-celosia argentia and Amaranthus hybridus grew poorly on all treatments. The statistical analysis showed a significant difference (p≤0.05) between Talinum triangulare grown in soil treated with digestate (plant height = 23.50, plant number =10 at day 7) compared with those treated with NPK (plant height = 18.50, plant number = 6.50 at day 7). The plant height and number for untreated soil at day 7 were 10.90 and 5.0 respectively). The Illumina sequencing of the digestate revealed the presence of some beneficial soil bacteria including Clostridium, Bacillus, Pseudomonas, Actinobacteria, and Micrococcus. The presence of these bacteria known to be Nitrogen fixers and Phosphate solubilizers confer biofertilizer potential to the digestate.
