Figure 14.22 Hydrogen isotope ratios of CJ6 oand Cis.-o fatty acids in modern horse milk and adipose fat, both from Kazakhstan (a), displaying seasonal influences [ellipses are 68 % (la) confidence intervals], compared (b) with 8 D values recorded for fatty acids from Eneolithic cooking pot sherds from Botai residues assigned as equine fats based on 813C analysis. Confidence ellipses are la and correspond to the modern reference equine fat values (Outram et al. 2009)...

In addition, seasonal variations may also influence the levels of APIs found. A seasonal influence on the FQs and TCs detection frequency in Coimbra (Portugal) municipal and hospital wastewaters was reported [34, 55]. Seasonal variations of up to a factor of four were also reported in a Finnish river [99, 100]. Seasonal variations can also affect the efficiency of WWTPs and river discharges since in winter the microbial activity is reduced due to low temperatures and the dilution effect is higher. Ultimately, at a wider level, geographical situation and climate may also explain different contamination scenarios between countries in different climatic zones [99, 100].

Mean drying time for the oven tray process is 19.2 hr. All 15 batches were dried within the specified time of 16 to 20 hr. No seasonal influence was apparent. The average moisture content of these batches is 1.2% the standard deviation is 0.3%. The 15 batches dried using the fluid bed dryer had a residual moisture of 0.8% (SD = 0.1%). Drying time is mechanically controlled and not recorded. The statistics favor the fluid bed process it is more efficient and uniform. There is nothing in these data to disqualify the oven tray dryer from further use, however.

Long-term cyclical changes also affect laboratory results. Seasonal influences and the menstrual cycle are examples of such changes.
