Abstract

Mediterranean forests dominated by Quercus species are of great ecological and economic value. The Quercus pollen season, peaking in April, varies in concentration due to geographical and climatic factors and has a remarkable allergenic potential. This study investigates Quercus trends in the Alentejo region of Portugal and examines the influence of meteorological parameters on DPC, PSD and SPIn, as well as the impact on allergic respiratory disease. The results show a progressive increase in Quercus Forest area from 1995 to 2018. Temperature and Precipitation are a key factor influencing pollen concentration, especially before peak of pollen season and prior to the pollen season. Particularly prior to the season, the precipitation of t-6 before influence, significantly, the pollen production. On the other hand, Global Srad and RH determine the beginning of the season. Using quartile-based categorization and multivariate statistical analysis, we identified years and scenarios within the IPCC projections where meteorological conditions influence may SPIn production. The study found a statistically significant correlation between high Quercus pollen concentrations in April and increased antihistamine sales. These findings are crucial for enhancing pollen forecast models and early warning systems.

葡萄牙阿连特茹地区土地覆盖和柞树属花粉浓度的变化趋势：气候变化的影响和对健康的影响。

以柞树为主的地中海森林具有重要的生态和经济价值。柞树花粉季节在四月达到高峰，其浓度因地理和气候因素而异，具有显著的致敏潜力。本研究调查了葡萄牙阿连特茹地区的柞树趋势，并研究了气象参数对 DPC、PSD 和 SPIn 的影响，以及对过敏性呼吸道疾病的影响。结果显示，从 1995 年到 2018 年，柞树林面积逐渐增加。气温和降水是影响花粉浓度的关键因素，尤其是在花粉高峰期之前和花粉季节之前。特别是在花粉季节之前，t-6 之前的降水量对花粉产量影响很大。另一方面，全球降水量和相对湿度决定了花粉季节的开始。通过基于四分位数的分类和多元统计分析，我们确定了 IPCC 预测中气象条件可能影响 SPIn 产量的年份和情景。研究发现，4 月份柞树花粉浓度高与抗组胺药销量增加之间存在统计学意义上的显著相关性。这些发现对于加强花粉预测模型和预警系统至关重要。

期刊介绍： Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health. Subject areas include, but are not limited to: • Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies; • Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change; • Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects; • Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects; • Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest; • New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
