一、重金属污染的控制
在使用有意有机肥料时，需要注意其来源和成分复杂，可能含有铅等重金属污染物。因此，对于这些肥料的质量管理尤为重要。此外，在茶园作业中，如使用采茶机等机械时，应确保使用无铅汽油，并尽量远离交通密集区域。另外，在加工茶叶所用的合金材料中也存在铅污染风险，因此在制造接触茶叶零部件的材料时，不宜选用含铅或其他类似的不良材料。
二、农药残留的控制
首先，我们应该通过综合运用病虫害防治措施来保持茶园生态系统平衡和生产多样性，从而降低农药残留至规定标准范围内。我们鼓励采用农业防治、物理防治以及生物防治方法，如秋末修剪、土壤深耕、人工捕杀和灯光诱杀，以及保护天敌等手段。在化学防治方面，我们应遵循以下原则：
mastered the dynamic of pest and disease occurrence, and apply pesticides at the optimal timing.
Select pesticides based on different types of pests, proposing a list of recommended pesticide varieties for each type, with one or two primary options and one or two alternatives to rotate use.
When choosing pesticides, consider their efficacy, insecticidal spectrum, water solubility, degradation rate, and foreign residual limits (MRLs) standards to ensure safe intervals between applications.
In tea production, we prohibit the use of banned pesticides such as amiton phosphate trioxide (including all isomers), chlorothalonil (including all isomers), and pyrethroids containing hydrogen fluorene-9-carboxylic acid ester derivatives.
For Anxi Tieguanyin in terms of fertilizers used in farming households should be treated through harmless processing before application; the content of pollutants in organic fertilizers should comply with relevant standards for pollution-free tea or organic tea.
