Persian (Farsi) term or phrase: کانون (ریزگردها/آلودگی)
متوسط جمعیتی آلودگی هوا تو ایران در سال ۱۳۶۹ حدود ۲۸ میکروگرم بر مترمکعب بود، و این مقدار چیزی حدود ۱۰ درصد افزایش پیدا کرده. تو کل کشور اگه به نقشه‌ی ماهواره‌ای و نقشه‌ای که ما محاسبه کردیم نگاه کنیم می‌بینیم که ۲ تا کانون اصلی وجود داره: یه کانون مرکز و شرق کشوره که بیشتر ناشی از بیابونه ولی در نقاط شهرنشینی ما نقاط قرمز و سطوح بالای مهاجر رو که نگاه می‌کنیم

Using "center" for کانون makes the translation a little awkward to me (One center is in the central and eastern parts of the country); is it correct? What's your suggestion?

English translation:source - area
Explanation:
Two major sources of ......
Two major areas of......
""Major" sources are defined as sources that emit 10 tons per year of any of the listed toxic air pollutants, or 25 tons per year of a mixture of air toxics. These sources may release air toxics from equipment leaks, when materials are transferred from one location to another, or during discharge through emission stacks or vents
•"Area" sources consist of smaller-size facilities that release lesser quantities of toxic pollutants into the air. Area sources are defined as sources that emit less than 10 tons per year of a single air toxic, or less than 25 tons per year of a combination of air toxics. Though emissions from individual area sources are often relatively small, collectively their emissions can be of concern - particularly where large numbers of sources are located in heavily populated areas."
