ABSTRACT
Background & objectives: The World Health Organization (WHO) document released on the World No Tobacco Day, 2020, mentions that tobacco kills over 22,000 people worldwide every day either from its use or second-hand smoke exposure, which is one person every 4 sec. In 2003, the Cigarettes and Other Tobacco Products Act (COTPA) was enacted by the Indian government to control/regulate use of tobacco and tobacco products. Despite various amendments to this law, there has not been any appreciable decrease in tobacco use. The objective of this study was to assess the compliance level with sections 4-10 of COTPA in urban Puducherry in South India. Methods: Random sample survey of 13 wards was carried out in selected parts of the city of Puducherry. The estimated sample size was minimum 160 public places and point of sales (PoS) each. A pre-tested checklist was used to obtain information on compliance with COTPA. Statistical and spatial analysis was performed using STATA v12.0 and QGIS v2.14.21, respectively. Results: Eight per cent of public places, 0 per cent of PoS, 1.7 per cent of educational institutions and 48 per cent of tobacco packages were found compliant with COTPA specifications. The compliance in public places varied from 0 (bus stops) to 55 per cent (religious places). Interpretation & conclusions: The overall compliance with COTPA was found to be very low in urban Puducherry. In order to ensure proper implementation of the laws, effective enforcement with periodic monitoring of various sections of COTPA are needed.
ABSTRACT
ABSTRACT The Passaúna catchment is part of the Upper Iguaçu watershed and includes a water supply reservoir for over 500,000 inhabitants of Curitiba metropolitan region. The aim of this study was to establish the state of reservoir water quality, and whether it has undergone any recent medium- and long-term variations. A physical-chemical-biological assessment was undertaken using nine indicators and three indexes: Water Quality Index (WQI), Trophic State Index (TSI) and Shannon-Weaver Index (H') for macroinvertebrate diversity. Compliance with the prescribed quality standards for the water body was verified using frequency curves. Two WQI calculation approaches were contrasted to test for conditions of partial data unavailability. Temporal trends in key parameters were assessed using Spearman's rank correlation coefficient. WQI results from 1991-2014 indicated that the water quality may be classified as good and improved in the final decade of such period, while most TSI results were in the oligotrophic/mesotrophic range, but with no significant temporal trend. The biodiversity result of H'=1.6 obtained with data acquired in 2014 indicated a moderately degraded ecosystem that is typically associated with flow regulation and a degree of water quality impairment. Such a multi-indicator integrated physical-chemical-biological monitoring approach comprised a robust framework for assessments of medium-long term aquatic health.
RESUMO A bacia do rio Passaúna situa-se na parte superior da Bacia do Rio Iguaçu e inclui um reservatório de águas de abastecimento público para mais de 500 mil habitantes da região metropolitana de Curitiba. O objetivo deste estudo foi avaliar a qualidade das águas desse reservatório e identificar eventuais ocorrências de tendência temporal de variação. O estudo de características físicas, químicas e biológicas do corpo de água envolveu dados históricos e recém-adquiridos de nove indicadores e três índices: Índice de Qualidade das Águas (WQI), Índice de Estado Trófico (TSI) e Índice de Diversidade de Shannon-Weaver (H') para diversidade de macroinvertebrados. A conformidade aos padrões de qualidade prescritos foi analisada com base em curvas de permanência de qualidade de água. Duas formas de cálculo do WQI foram contrastadas para averiguar o efeito de disponibilidade incompleta de dados. Tendências temporais em parâmetros-chave foram buscadas com o teste de correlação de Spearman. Os resultados do WQI, entre 1991 e 2014, indicaram que a qualidade da água do reservatório pode ser classificada como "boa", apresentando tendência estatisticamente significativa de melhoria na última década de tal período. Os resultados obtidos para o TSI ficaram na faixa oligotrófico/mesotrófico e sem tendência significativa de variação temporal. O resultado de biodiversidade do H'=1,6, obtido com dados adquiridos em 2014, indicou um ecossistema aquático moderadamente degradado, tipicamente associado com o represamento de cursos de água e com um certo grau de comprometimento da qualidade da água. A abordagem integradora multi-indicadores de aspectos físicos, químicos e biológicos adotada neste estudo conferiu robustez à avaliação realizada da qualidade de água do corpo de água no médio-longo prazo.
