“…The average annual temperature varies between 18.7 °C and 21.0 °C. Concurrently, annual precipitation ranges from 1031 mm to 1369 mm, with sunshine durations between 1804 and 2060 h. Such climatic conditions favor the cultivation of subtropical crops and trees [20]. The predominant agricultural system in this region is a rice-tobacco rotation, optimized for tobacco growth [21].…”

In Longyan City, Fujian Province, a hub for premium tobacco in China, our study explored the connection between soil properties and heavy metal levels in tobacco leaves, focusing on chromium (Cr), lead (Pb), and zinc (Zn). We observed that the soil's average concentrations for Cr, Pb, and Zn were 0.165, 9.53, and 5.17 mg/kg, respectively. In stark contrast, tobacco leaves presented elevated mean concentrations of these metals, measuring 0.936, 2.19, and 102 mg/kg for Cr, Pb, and Zn, respectively. This disparity was further highlighted by the soil's exceedance rates for Pb and Zn at 2.93% and 0.472%, and the significantly higher enrichment coefficients in tobacco, 23.1 for Pb and 19.7 for Zn, compared to Cr, suggesting a substantial health risk. Our study identified critical soil parameters, including pH, organic matter, and levels of available potassium and phosphorus, as influential factors determining heavy metal content in tobacco. Utilizing these findings, we formulated predictive regression models for estimating Cr, Pb, and Zn concentrations in tobacco leaves. The regression models for estimating the concentrations of chromium, lead, and zinc in tobacco leaves are as detailed below: YCr = 0.889 + 0.001 * XK + 0.001 * XN - 0.005 * XOM + 0.101 * XCr (R2 = 0.852), YPb = 2.608 - 0.069 * XpH - 0.001 * XN + 0.008 * XZn + 0.01 * XPb (R2 = 0.738) and YZn = 101.892 - 0.141 * XP + 0.32 * XOM - 0.123 * XPb + 0.614 * XZn (R2 = 0.801), respectively. These offering essential tools for assessing and controlling heavy metal risks in tobacco cultivation within the region.

“…The NHP hosts some of the world's highest mountains, such as K2, Nanga Parbat, and Broad Peak. This region is a vital source of freshwater for millions of people living downstream, and it influences the hydrology and climate of South Asia [5]. Climate change has caused various changes in this region, affecting both the mean and extreme climate conditions.…”

This study utilized hot and cold indices to evaluate the changes in extreme temperature events that occurred in subtropical highland climates from 1991 to 2020. The modified Mann–Kendall (MMK) test and the Theil–Sen (TS) slope estimator were used to analyze the linear trends in the time series of the extreme temperature indices. The northern highlands of Pakistan (NHP) were considered as a case study region. The results showed that the annual maximum temperature had a slightly increasing tendency (at the rate of 0.14 °C/decade), while the annual minimum temperature had a slightly decreasing tendency (at the rate of −0.02 °C/decade). However, these trends were not significant at the 5% significance level. The decadal averages of the hot indices were the highest in the second decade (2000s), while they were the lowest in the subsequent decade (2010s). In comparison, all the cold indices except the annual minimum value of the maximum temperature (TXn) showed a persistent decline in their decadal averages throughout the 2000s and 2010s. Overall, the frequency of hot days significantly increased in the NHP during the study period. This study found that the hot days and coldest days increased over the past three decades in the NHP. However, there was a decreasing trend in the cold spell duration, cold nights, and the coldest nights over the past three decades, as demonstrated by the trends of the cold spell duration index (CSDI), the temperature of cold nights (TN10p), and the annual minimum value of the minimum temperature (TNn) indices. These changes may impact the environment, human health, and agricultural operations. The findings provide useful insights into the shifting patterns of extreme temperature events in northern Pakistan and have crucial implications for the climate-change-adaptation and resilience-building initiatives being undertaken in the region. It is suggested that the continuous monitoring of extreme temperature events is necessary to comprehend their effects on the region and devise strategies for sustainable development.
