An investigation into parametric relationships between enterovirus and faecal indicator organisms in the coastal waters of England and Wales

摘要: Previous research has resulted in conflicting conclusions concerning possible statistical relationships between bacterial indicator and enterovirus concentrations marine waters. Results have suggested either highly significant or no correlation. To examine these further, large compliance assessment data sets for identified bathing waters on the English Welsh coast, 1988 1992, were extended to include faecal streptococci counts addition total coliform data. The suitability of parametric correlation analysis was assessed by examining nature distributions raw residual values from regression analyses. acceptable when (i) zero samples excluded (ii) logarithmically transformed. over 690 pairs produced positive Pearson coefficients coliforms, concentrations. Though correlations (P 99.9% confidence) they low (r < 0.5). amount variance concentration explained only 15–16%. Relationships similar each determinand. Correlations above successive quartile revealed threshold effect relationships. These results suggest poor indicators sewage pollution resulting a predictive capability.
